Do remember that Which? reports are based on their members' views. When colout tv started they quite liked a Fergusson 19" model, but slated an HMV
19" as very unreliable. Yet, the only difference was the cabinet. Some years later, I came across the documentation behind the report. There were on 2 HMVs reported on and one developed a fault. (as mine did, but it was a dry joint off the main board which I resoldered)
